These bolts or tachment involving theprinciples of the threaded rods are provided with nuts 15, by invention.a which the plate 6 is clamped against the Fig. 2 is a side elevation ofthe structure boiler front, and with nuts 16 which bear shown in Fig. 1.against the flange 11, and thereby draw the Fig. 3 is anenlarged,'vertical, longitudinal header into tight engagement with theplate sectlonof the water-heating ,unit shown in 6, with gaskets orpacking 17 between the Fig. 1, with certain portions of the water edgesof the header and the seat formed, as tubes broken away for convenienceof illusshown, in the face of the plate 6, thereby tration. forming atight joint to prevent leakage.

Fig. 6 is a similar view, showing a difierent .then out through thepipe 9, and through the form of theinveution. pipe 19 to sea tank 3,thus circulating the viously described, having the other leg into sameas the one shown in heated water absorbed from the body of hot water inthe boiler into the water circulating through the pipes 4 of theauxiliary heating unit.

. Fig. 5 shows a construction similar to that shown in Fi but in thiscase the tubes 20 are given a orty-five degree twist, as shown, therebyto facilitate the circulation of the water therein.

' In Fig. 6 the construction is similar to that shown in Fig 3, butinthis case the tubes provide a group of two bends for each of thechambers or compartments 7 and 8 of the header, so that water flows outof one compartment or chamber through a plurality of tubes, and thenback through a plurality of tubes into the other compartment or chamber.

In Figs. 7 and 8, the construction is similar to that shown in Fig. 3,but in this case there is also a difference in the arrangement of thetubes. In Figs. 7 and 8 the header and plate construction, held by boltsto the front of theboiler, are the same, and the header has the twochambers 7 and 8 prethe pipes 9 and 10 in communication therewith. Inthis case, however, the plate 22 is some hat different from the plate 6,being provided with six openings for six tube ends, as followsWaterenters the compartment 8 through the pipe 10, and flows out of thiscompartment through one leg of the U-shaped pair of tubes 23, and backthrough the other leg of this pair of tubes into the passage 24: in saidplate, and then out through one leg of the U-shaped pair of tubes 25,and back through the passage 26 formed in said plate, and up throughthis passage into one leg of the pair of tubes 27, and then back throughthe other leg of this pair into the com artment 7 as indicated by thearrows in Figs. 7 and 8 of the drawings. With this arrangement, thewater is circulated back and forth six times, after leaving the header,

be' like the one shown in Fig. 3, or the one shown in Fig 5, or the oneshown in Fig. of the drawings, having the header provided with the sametwo compartments and 8, and having the pipes 21 shown in Fig. 6 of thedrawings. ith this arrangement, the heat of the water in the tank 29 isabsorbed by the water in the tubes 21, and hence t water Which entersthe header through pipe 10 has its temperature raised considerably, andfinally escapes from the header through'the pipe 9, as previouslyexplained. In Fig. 11, the construction is similar to that shown at theright in Fig. 10, but in this case the tubes 32 of the heating'unitterminate in'a single compartment header 33, as shown, so that the waterflowing through the different tubes from the compartment 8 is all mixedtogether when it enters the header 33, before traveling back through thetubes which lead to the compartment 7, in a manner th In each form ofthe invention, it will be seen that the heating plate and header areprovided with packing or gaskets between them, like the packing orgaskets 17 shown in Fig. 3. This provides a tight joint to preventleakage between the plate and the header, the plate being held tightlyto the front of the boiler, or to the front of the tank containingwater, and thereby preventing In each case, also, only the removal ofthe outer nuts 16 is necessary 0 detach the header from the boilerfront, or from the tank structure, thus leaving the plate 6, in

The plate in this way forms seat, as it can be removed by taking off thenuts 15 after the removal of the header, but the seat provided by theplatedoes not need to be removed when the header is removed. When theheader is removed, without removing the plate 6, in each form of theinvention, the tubes remainheld in place by before it returns to theheader, and with this the plate, and leakage from the boiler does o g rPerlod 0f l n h Water ahnot occur, as the removal of the header sorbsmore heat from the b0 dy of water in the boiler, and is raised to aalone does not cause any such legkage.

I

The heating unit shown in Fig. 10 is inserted in the end of the tank 29,as shown, and this heating unit is substantially the Fig. 6, or it mayplate and'tubes portion of the unit to the boiler first, or to the tankfirst, thus, in any form of theinvention, closing the 'opening in thewall of the boiler or tank and then the header portion of the auxiliaryheating unit isplaced in position and secured by the tightening of thenuts 16, as shown and described.

As shown in Fig. 12 of the drawings, the tubes can be oval in crosssection, if desired, thus increasing the efiective'surface of the tubes,while not increasing the width of the header. For example,in Fig. 3 ofthe drawings, the pipes 4 can be oval incross section, without changingthe relative proportions shown in Fig. 3, by locating the minor axes ofthe ovals in parallel planes, so that the broader sides of the tubeswill be opposed to each other. This oval formation of the tubes, it willbe seen, can be used in any of the different forms of the invention, ordifierent arrangementpf tubes,

forms of header, or

Without disclaiming anything, and without prejudice to any noveltydisclosed, what I claim as my invention is:

1. In a heating apparatus unit, the combination of a support having anopening therein through which the heating unit is inserted, a plateaccessibly secured to the outer side of said support and forming a seatat the outer side of said opening, tubes having their open end portionsrigid with said plate and extending through said opening, the plate andtubes forming a closure for said opening, a header havin compartmentsfor incoming and outgoing ui'd,with inlet and outlet means for saidcompartments, and securing means for accessibly and removably holdingsaid header on removal of said plate exce t by first detaching saidheader therefrom,

ut permitting re- 'moval of the header alone while said plate withoutdisturbing said first mentioned nuts.

A structure as specified in claim 1, havingmeans in said seat forming a tight joint between said header and plate,preventing leakage from saidcompartments of the header, said supportbeing the wall of a boiler or tank, and said plate preventing leakagefrom said boiler or removed. v

4. A structure as specified in claim 1, said securing means comprisingthreaded rods fixed in said support, both the plate and the header beingremovable from said rods, leaving said rods fixed in said support.
